We used a periodically constricted pipe model as a surrogate for a homogeneous porous medium with pore vortices. With FLUENT software, we simulated solute transport and generated solute breakthrough curves (BTCs) along this pipe. Even with a significant presence of vortices, we find that Taylor dispersion develops given sufficiently lcaig travel distance or travel time，as is the case for a straight capillary tube. However, in the pre-Taylor domain, the BTCs are described by fractional dispersion
